One goal of a social network, as its name suggests, is to provide human beings with a digital platform where they can build social relationships with a spectrum of people they choose. In this paper, we build a new model that uses Facebook data to measure inter-communication between segregated communities in Lebanon, a country whose diverse yet divided social mosaic is a result of a long history of power struggles and consensus periods between different religious groups. Two case studies are conducted and results are used to validate a conceptual basis by French intellectual Dominique Wolton. Varying results confirm Wolton's ideas about technology's ability to only speed up communication but not to help people overcome social and demographic boundaries.
